Low energy consumption, together with high productivity and stable blast furnace operation, has been achieved at Rautaruukki's Raahe Steel Works as a result of the efficient use of computer technology in process control and improvements in raw materials quality. The blast furnace supervision system is designed to support the decision-making in medium and long-term process control. The information presenting the blast furnace operation phenomena is grouped so that little time is needed to obtain the current state of the process. Due to the complexity of the blast furnace process, an expert system to guide and diagnose the short and medium-term blast furnace operation has been developed.
